Embodiment Construction

[0019] The present invention provides a composite brightness enhancement film and a backlight module. In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] See Figure 2 to Figure 4 The composite brightness enhancement film of the present invention includes a transparent film layer 2, a light-concentrating layer 21, and an atomization layer 22. The light-concentrating layer 21 and the atomization layer 22 are integrated with the transparent film layer 2, and the light-concentrating layer 21 and the atomization layer The layers 22 are arranged relatively.

[0021] The material of the transparent film layer 2 is polyethylene terephthalic acid (PET). The thickness of the transparent film layer 2 is about 50 microns.

[0022] The light-concentrating layer 21 is a V-cut light-concentrating stru...

Abstract

The invention discloses a composite bright enhancement film, comprising a transparent film layer, a light collecting layer and an atomizing layer, wherein the light collecting layer, the atomizing layer and the transparent film layer are integrally arranged; the light collecting layer and the atomizing layer are integrally arranged. The composite bright enhancement film adopts a single-layer structure design, and uses a saw-tooth shaped refraction surface of the light collecting layer to enhance the bright. The light is diffracted by beads with different convex hemisphere grain sizes arranged on the atomizing layer, thereby achieving atomizing and diffusing effects. Compared with the traditional backlight module, the composite bright enhancement film can reduce more than one diffusion film, and can reduce the manufacturing steps of double coating the multi-layer diffusion films in the traditional manufacturing process, thereby greatly reducing the cost and improving the operating quality.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a composite brightness enhancement film. Background technique [0002] The traditional liquid crystal display (TFT-LCD) is mainly composed of a liquid crystal panel and a backlight module. The structure of the traditional backlight module is as figure 1 As shown, the backlight module has a light guide plate 11, the bottom surface of the light guide plate 11 is provided with a reflective plate 110, the light entrance surface of the light guide plate 11 is provided with a light source 10, and the light exit surface of the light guide plate 11 is provided with a first diffusion film 12, Two layers of brightness enhancement film 13 are arranged on the first diffusion film 12, and finally a second diffusion film 14 with protective effect is added. [0003] The backlight module of this structure needs to use more optical films, the cost is higher, and the light source ...
